Which Country Has The Most Superior 5th-Generation Fighter Jets In The World?

Which country has the most advanced fifth-generation fighter jets? The short answer is the US, on account of the Lockheed Martin F-35 Lightning II and the Lockheed Martin F-22 Raptor, although there is more nuance to the topic. TheF-22 Raptor may have been the most advanced fighter jet in the 2000s, but its massive costs led to its early cancellation. Meanwhile, production difficulties of the Su-57 mean Russia is unable to ramp up production.
